Modelling is not just a matter of removing irrelevant detail. It is also about identifying and isolating the different dynamical systems that are at play so that we can build an intuition for how a complex system behaves. Even if the factors that you are describing are important to the overall outcome, it may still be useful to explore a model with those factors removed.
